Help! Breastfeeding and weaning.

So I have EBF for the last 6 months. During that time my little man would talk bottles of expressed milk. I have decided that our breastfeeding journey is over but I have no idea where to start with weaning. I have tried to cut out feedings during the day but now he refuses to take the bottle from me period weather it’s formula or breast milk. He stayed with my family for a few hours and he did finally take breast milk from his bottle but refuses formula. I have also tried 3 different formulas: enfamil neuron pro, enfamil neuro pro gentle ease and similar pro advance. He will also fight his sleep until he is nursed. Help a momma out. Looking for advice on weaning not on why I should continue breastfeeding.
